SPECIFICATION forming part of Letters Patent No. 294,649, dated March 4,1884.

v Applica-tion filed August 17, 1883. (No model.)

To alli/)71.07111 it may concern/.-

Beit known that I, DAVID B. MATLOCK, a citizen of the United States ofAmerica, residing at Red Bluff, in the county of Tehama and State ofCalifornia, have invented certain new and useful Improvements in Gates;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the saine.

My invention appertains to ilnprovements in gates'of that class whereinthe passage is opened and closed by the vertical movement of the gate.

It is the object of my invention to construct a gate of the kind namedwhich can be readily and easily raised from a closed position or closedfrom a raised position by a person in a road-vehicle or on horsebackwithout gettinglout of the vehicle or dismounting.

My improvements therefore consist in providing the gate withguide-plates carrying friction-rollers operating against the side posts,

, in combination with latching means, as hereinafter set forth. y

My improvements further consist in an improved latch whereby the gate iscertainly latched and securely held in a raised position.

vMy improvements also consist in the novel construction and combinationof parts, as will be hereinafter more fully described and speciiica-llyclaimed.

In the accompanying drawings, forming a part of this specification,Figure l is a perspective view of my improved gate. Fig. 2 is a viewshowing a section of the gate with the friction-rollers and latchprojections. Fig. 3 is a view of the latch and alarm, and Fig. 4

is a view of the slotted guides and frictionrollers.

The letter Arepresents the uprights, connected at the top byasubstantial cross-tic, a, and further stiffened and secured by theanglebraces b. In the cross-tie, on a line with the fall of the gateandv theweights, are formed inortises or holes c, for receiving thecords which sustain the gate in suspension; and on the cross-tie,preferably over the uprights and between the holes for the cords, aresecured the groove cord-pulleys B and B. The

angle-braces C at the base of the frame are secured at their upper endsto the uprights by any suitable means. l

The letter D represents cross-bars which have one end fastened to theupright, and from thence extending', cross each other, and, reach fromthe uprights far enough to serve the purpose of carrying the cords adistance from the gatesufficient to permit the team to stand between thegate and the operator in the wagon or other vehicle. Secured to thecenter of the cross-tic of the frame, on each side, are the braces d,the other end of which is secured to the cross-bars D at the place wherethey meet and cross each other. Ihc ends of the cross-bars D areconnected and further strengthened by a bar, c, substantially as shown,and these frames are further secured and braced by the metallic rods f,secured to the main cross-tie of the frame'at near the upright, and fromthat point extending, having their other end secured to the ends of thecross-bars. To the ends of the cross-bars D are secured grooved pulleysg, g', g, and 9', and in the center of the cross-tie a are fixed thepulleys It and 7L', over which are passed the cords which lift the gate.

The letter E represents the gate, which may be of any suitableconstruction, so far as the frame-work is concerned. To the end slats orbars of this gate are bolted the guide-plates t', formed with slottedbolt-holes j, for the purpose hereinafter stated, and havingjournalholes k, in which the journals of the frictionwheels Zjournal.rIhese friction-wheels are placed, as shown, between these guides, andbear with their faces against the faces of the posts. By means of theslots in the guideplates the friction-wheels may be adj usted toaccommodate any swell or shrinkage of the gate or frame. It will be seenby reference to the drawings that the guide-plates are of unequallengths, one shorter than the other. The longer one is intended toextend far enough across the face of the upright to certainly engagewith the latch, and the shorter one is made of such length that in theascent or descent ofthe gate it will not encounter any obstacle in itscourse. These guides also keep the gate in a vertical p osition, and, asintimated,

IOO

the longer one acts as the means for holding the gate when in contactwith the latchthat is, the upper one secures the gate in the lowerposition and the lower one in a. higher position. The gate is suppliedwith the common cords and weights n, the cords being passed over thepulleys on the upright., and having suspended weights attached lighterthan the gate. To the center of the gate are attached the lifting orhand cords o, which pass `from the point. oit' suspension up throughholes in the cross-tie over the pulleys 71 and h', and from thence overthe pulleys f/ and y, and have smallweights attaehedto them suilieicntto hold them in position. rlhese cords are disposed, respectively, tothe right hand in the direction ot' travel, for obvious reasons.

The letter F represents my improved alarm and means for securing thegate ata iixed height. In one of theuprights is cut a slot, p, (see Fig.3,) of suitable width and length, vfor the purpose of receiving thealarm and latchlcver. vlfn this device the letter l represents theactuating-lm'er iournaled to its i'ulerum r, iXed in the upright,preferably formed with the bow shape shown, and having pivotallyattached its lower arm the latch s, which rests on a bar er pin, i,passed through the slot in the post, in such position that the free endof the latch cannot be drawn back past the pin l or fall 'from its lineot' engagement with the gate. lo the rend ofthe bent arm ofthe lever areattached the cords yu n', one of which, n. passes through a` hole, y, inthe upright, and from thence to the pulley y", and the other, n, passesabout a grooved pulley, r, and from thence to the pulley y, as shown. Inorder to assure prompt action in the movement ot the latch after thegate has passed in descending, a weight, lze, may be attached to thebent arm of the lever, substantially as shown in Fig. 3.

The letter lf represents the alarm, which consists of the bell fixed tothe upright, and the clapper u, journaled to a rod passed throughtheslot, and so disposed and adjusted that when the gate, in its upwardpassage, lifts the latch and passes from contact therewith the latch, infalling back, strikes the end of the clapper and drives it against thebell, which is a signal that the gate has passed above the latch andwill drop and rest thereon when the hand is released from the cord.

To set the gate in position, the upright may be set in the ground orsecurely bolted to posts set in the ground, and the angle-braces at thebase similarly secured or set.

In order to take up the slack in the liftingeords and prevent them fromgetting in the dirt and mud, I extend the cords from the rI`he gate isthen in position to admit of the passage ol.' the vehicle or horse.After passing through, the cord n or u. on the right-heing the oneconnected from that side with the end of the latch-leveris pulled, whichwithdraws the bar of the latch from contact with the guide, andthe gateby its own weight deseends.

To prevent hogs or other animals from .raising the gate, I stretch abarb-wire beneaththe bottom rail ot' the gat e or supply it with pointedspikes in thc lower rail.

YVhatIelaim as myinvention, and desire to secure by Letters Patent, is-

l. ln combination` with the verti 'al sliding gate provided withguide-plaies of unequal lengths, the longer of which is adapted toengage with a locking means, the locking-lever pivotally attached in theuprights ofthe gateframe, substantially as described.

2. In combination with a vertical gate having extended guide-plates, thelatch consisting oil' the lever gj and latch-bar s', substantially asdescribed.

3. In combination with a vertical sliding gate having extendedguide-plate, the latch consisting of the lever q and latch-bar s, and sinal lever and bell, substantially as described.

4. In combination with a. vertical sliding gate having extendedguide-plates, and cal'- rying friction-wheels journalcd therein, thelatch consisting ofthe lever j and latch-bains, substantially asdescribed.

5. In combination with a vertical sliding gate having adjustableextending guide -plates carrying friction-wheels iournaled thereon,thelatch consist-ing ofthe lever j and latch-bars, substantially asdescribed.

t5. In combination with the hand-cord o, a cord secured thereto andconnected with the cord or weight to draw up the gate, substantially asand for the purposes setI forth.

In testimony whereof I affix vmy signature in presence of two witnesses.
